The Madison County Sheriff’s Office is trying to determine what happened to some two dozen animals found dead on a farm south of Van Meter Tuesday.

Chief Deputy Jason Barnes says officers investigated a farm just east of Highway 169 and south of Interstate 80. According to Barnes, authorities found 25 dead cows of the approximately 200 head of cattle.

Deputies are continuing investigation into the cause of death. Barnes reports that a veterinarian is assisting to determine the welfare of the rest of the cattle.
